#啟用有頭模式
chrome_options = webdriver.ChromeOptions()
#chrome_options.add_argument('--headless') # 啟動無頭模式
#chrome_options.add_argument('--disable-gpu') # windowsd必須加入此3
driver = webdriver.Chrome(ChromeDriverManager().install(),chrome_options=chrome_options)
driver.get('https://bbs.bccn.net/forum-246-1.html')
driver.set_window_size(1000, 1000)
driver.implicitly_wait(20)


#手動登入帳號
time.sleep(20)


#啟用無頭模式
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless') # 啟動無頭模式
chrome_options.add_argument('--disable-gpu') # windowsd必須加入此3
